Unicode Error

Hello All,

I have following code:

WRITE:/ T510N, 'T510N WAS changed'.

where t510n, is a pooled table...with all types of fields...I mean..char, dates, currency etc...

It was working fine before the unicode upgrade...but now after doing the unicode upgrade...gives following error:

"T510N" cannot be converted to a character-type field.

Any help would be greatly appreciated....

Thanks in advanced.
